That was some story and I know that once you passed the fear stage, you were relieved to learn that Fletcher is such an awesome and fiercely protective dog. I do believe Fletcher saved your life without a doubt and he probably inadvertently saved the crook's life because had anything happened to you I'm sure hubby would have hunted him down and killed him!
It did concern me that you opened the door. For the people reading, never, ever open the door. Never, Ever, Ever.
